In an interview with the Boston Herald, Perry lashed out at the rock frontman for having found out on the Internet that Tyler intended to judge the Fox singing competition.

“I mean, after working with me for 40 years, he couldn’t tell me about this,” Perry told the Herald. “Why so secretive? We’re told it’s a done deal. If Steven is committed to a TV show, that kind of affects the rest of us. We’d like to plan our lives, ya know?”

Fox execs have not confirmed which judges they plan to replace Simon Cowell or Ellen DeGeneres with, though reports have said both Tyler and Jennifer Lopez are close to inking deals. On Thursday, the network announced that original producer Nigel Lythgo had returned to the show for its 10th season.

Perry said when he confronted the "Amazing” singer about the “Idol” rumors, Tyler said he was told not to talk about it.

Relations between Tyler and the rest of the band have reportedly been rocky for years.

An injury last summer where Tyler fell off the stage forced the band to cancel its tour, and Tyler went into rehab for an addiction to painkillers.
